Photography is about light. Learning how to see light is essential to developing your photographic eye. When taking pictures, being able to determine the intensity, color and direction of the light will help you know how to position your subject and which camera settings to use- Heather Bettison

Mari kita lihat apa itu natural lighting photography..

Natural light photography adalah cahaya yang dihasilkan secara natural tanpa menggunakan peralatan flash dan reflector untuk mengubah cahaya pada keadaan yang sedia ada. 


Specular Light vs Diffused Light ( source : here)

Specular light is the direct light from the sun (or other light source) that falls on the subject. As already mentioned, it can add or take away from the quality and interest of your photographs. Specular light is necessary for highlighting parts of the picture. For instance, it creates texture and interest when used properly.
Diffused light is light that has passed through some type of filter, softening the effect of the light. With respect to natural conditions, clouds are the most effective of all excellent diffusers. Also, when you place your subject in a shady area, you are effectively using natural diffusers to lessen the specular light. Diffusing the light decreases the dynamic range of light so that the camera has a better chance of interpreting the light with the same accuracy as the human eye.

Specular VS Diffused

The difference here is only about 3 feet from sun to shade. The sun creates shadows and "hot spots" in the pictures with specular light. The trees create a kind of light diffuser that enables the camera to better interpret the light in a more pleasing image.

Manakala artificial lighting pula:

Artificial lightning di dalam fotografi pula adalah dengan menggunakan sumber cahaya dari alat tertentu untuk menghasilkan pencahayaan.

Artificial light sources are other sources of light which developed to compensate for or assist the natural light. It will have different frequencies and wavelengths that determine the light color.

Artificial light sources   ( source : here)
  The five most common light sources are as follows:

  1. Incandescent lamp. 
  2. Compact fluorescent lamp. 
  3. Fluorescent tube. 
  4. Discharge lamps. 
  5. Light Emitting Diode (LED).
